Effect of Normal Contact Vibration on Nano-Scale Friction

Lubricants, 2019
In this work, we investigate the effect of contact vibration on the friction of sliding single asperity contacts of different adhesion strength over a wide range of load and vibration amplitude.

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

Lubricant Additives for Improving the Performance of Metal V-Belt Type CVTs

Tribology Online, 2012
Lubricants for metal V-belt type CVTs (B-CVTFs) must be able to produce a higher metal-metal friction coefficient and give excellent anti-shudder properties for lock-up clutch used in B-CVTs.

AFM-Fold: Rapid Reconstruction of Protein Conformations from AFM Images

Biophysical Journal
Abstract High-speed atomic force microscopy (HS-AFM) enables direct visualization of protein dynamics under near-physiological conditions, yet its intrinsic limitation to surface topography prevents atomic-level structural characterization.

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

MOS based nanocapacitor using C-AFM [PDF]

, 2003
Nanocapacitors are integral devices of nanoscale MOS based integrated circuits and have not yet been realised. We report in this article our results to date on the realisation of such a nanocapacitor through the use of Atomic Force Microscopy (AFM ...

Interactive Strength between C60 Thin Film and Si(001) and Its Influence on Nano-Scaled Tribology

Tribology Online, 2008
The influences of interactions between C60 thin films and Si substrates were investigated using atomic force microscopy (AFM). It was found that higher friction coefficient was obtained at the C60 domains formed on the H-terminated Si(001) substrate and ...

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,
